in reply to Changing effecive user id
For the second part "group ids haven't changed", you need to reverse the order of your assignments, since once you've changed your UID you probably don't have enough permissions anymore to change the GID.
For the first part, my perl gives me a
error so I can't quite test it.$ /tmp/k Can't do setuid (cannot exec sperl)
Update: I installed perl-suidperl so now it works. It looks like the setuid bits aren't working for you, since the effective UID/GID when run as yourself should still show as root if the file is owned by root and has the setuid bit set:
$ id -u 1000 $ id -g 1000 $ /tmp/k Current Effective User ID: 0 Current Effective Group IDs: 1000 1002 1001 1000 Requested User ID: 1001 Requested Group ID: 55 Changing Effective IDs Current Effective User ID: 1001 Current Effective Group IDs: 55 1002 1001 1000
